DX52D + Z phaj yog dab tsi?

DX52D + Z phaj yog dab tsi?
DX52D+Z phaj yog kub-dip galvanized phaj. "DX" stands rau kub-dip galvanizing, "52" xaiv cov qib stamping, uas muaj cov formability zoo heev, "D" xaiv cov hlau tiaj tus, thiab "+Z" qhia cov zinc txheej ntshiab.
Dab tsi yog cov qauv DX52D + Z phaj ua raws li?
Nws ua raws li Suav teb tus qauv GB / T 2518-2019 thiab kuj ua raws li European qauv xws li EN 10346-2015.
Dab tsi yog qhov txawv ntawm DX52D + Z phaj thiab DX51D + Z phaj?
DX52D + Z phaj muaj kev tsim tau zoo dua li DX51D + Z phaj. DX51D + Z yog qib kev lag luam dav dav nrog lub zog muaj zog, thaum DX52D + Z yog qib stamping nrog lub zog qis dua me ntsis, ua rau nws tsim nyog rau stamping.
Tshuaj muaj pes tsawg leeg
Dab tsi yog cov tshuaj tseem ceeb ntawm DX52D + Z phaj?
Cov tshuaj lom neeg tseem ceeb muaj xws li carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), thiab titanium (Ti). Cov ntsiab lus carbon feem ntau tsis tshaj 0.1000%, thiab cov ntsiab lus manganese tsis tshaj 0.6000%.
Cov tshuaj muaj pes tsawg leeg cuam tshuam li cas ntawm DX52D + Z phaj?
Cov ntsiab lus carbon tsawg ua kom zoo plasticity thiab formability; manganese txhim kho lub zog thiab toughness. Ntau cov phosphorus thiab sulfur cov ntsiab lus txo cov hlau qhov toughness thiab corrosion kuj, yog li lawv yuav tsum tau tswj nruj me ntsis.
